In Section 2, Travis Goodspeed will show you how to build your own antiforensics hard disk out of an
by simple patching of the open source Rockbox rmware. The result is a USB disk, which still plays
music, but which will also self destruct if forensically imaged.
In Section 3, Julian Bangert and Sergey Bratus provide some nifty tricks for abusing the dierences in
ELF dialect between exec() and ld.so.
As an example, they produce a le that is both a library and an
executable, to the great confusion of reverse engineers and their totally legitimate IDA Pro licenses.
Section 4 is a sermon on the subjects of Bitcoin, Phrack, and the den on iniquity known as the RSA
Conference, inviting all of you to kill some trees in order to save some source. It brings the joyful news thatwe should all shut the fuck up about hat colors and get back to hacking
Delivering even more nifty ELF research, Bx presents in Section 5 a trick for returning from the ELF
loader into a libc function by abuse of the IFUNC symbol
. There's a catch, though, which is that on amd64
her routine seems to pass a very restricted set of arguments. The rst parameter must be zero, the second
must be the address of the function being called, and the third argument must be the address of the symbol
being dereferenced. Readers who can extend this into an arbitrary return to libc are urged to do it and share
the trick with others!
Remembering good times, Section 6 by FX tells us of an adventure with Barnaby Jack
, one which features
a golden vending machine and some healthy advice to get the fuck out of Abu Dhabi.
